如何从asp.net中的FileInfo获取文件扩展名用c#

Question

请看下面的代码:

    foreach (FileInfo f in dir.GetFiles("*.*"))
    {

        Files += "<div class='divFilesBody_Row'>";
        Files += "<div class='divFilesBody_Left'>";
        Files += "&nbsp;";
        Files += "</div>";
        Files += "<div class='divFilesBody_Name'>";
        Files += "<img class='imgFile' src='~/Images/Download/file.png' />";
        Files += "<span class='FileName'>";
        Files += f.Name;
        Files += "</span>";
        Files += "</div>";
        Files += "<div class='divFilesBody_FileType'>";
        Files += f.??????? 
        Files += "</div>";
        Files += "<div class='divFilesBody_FileSize'>";
        Files += f.Length;
        Files += "</div>";
        Files += "<div class='divFilesBody_FileCreationDate'>";
        Files += f.CreationTime;
        Files += "</div>";
        Files += "<div class='divFilesBody_FileDownload'>";
        Files += "<a class='FileLink' <a target='_blank' href='../Files" + lastpath + "/" + f.Name + "'>";
        Files += "<img class='imgDownload' src='~/Images/Download/Download.png' />";
        Files += "</a>";
        Files += "</div>";
        Files += "<div class='divFilesBody_Right'>";
        Files += "&nbsp;";
        Files += "</div>";
        Files += "</div>";
    }

看看这一行:
f.???????

如何使用.net方法获取f(FileInfo)的文件扩展名？

使用f.Extension.或者,您可以使用Path.GetExtension(f.FullName)

Files += "<div class='divFilesBody_FileType'>";
Files += f.Extension;
Files += "</div>";
